IMPROVEMENT IN NAPPlNafBRusHINe, AND cALEnDEaiNe MACHIaEs.

Specification forming part of Letters Patent No. 172,690, dated January 25, 18,76; application filed October 23, 1h75.

To all whom it may concerner Be it known that I, NroHoLns J. BECKER, of Amsterdam, in the county of Montgomery 'and State of New York, have invented a new This invention has relation to machinerywhich is designed for raising the nap or pile on woolen and cotton fabrics, also for brushing and calendering the same.

The nature of my invention consists in the combination of napping, brushing, and calendering mechanism, and also in a novel spreader or stretcher for use inside of tubular work, for the purpose of giving the same the proper width and evenness in calendering, as will be hereinafter explained.

In the annexed drawings, A designates the frame of the machine, and B the main driving shaft, on the ends of which are belt-pulleys a a b b. The main driving-belt plays on the pulleys b b', the latter one being a loose pulley, which, with a beltshipper, c, actuated by a lever, c', from the front of the machine, will enable the attendant to stop and start the machine at pleasure. B B designate two nappingcylinders, which are covered with napping cards or teasels, and arranged one over the other. The shafts of these cylinders have their bearings in elevated portions of the frame A, and pulleys d d are keyed on said shafts, which receive crossed and straight running belts, driven by pulleys a a 011 the main shaft B. Cylinders B are rotated in 4the directions indicated by the arrows, Fig. 2, and perform the operation of raising the nap on the fabric passed between them. C C designate two friction-rollers, between which the fabric is drawn on its way to the napping-cylindersu. These rolls are very important, as they hold the fabric under proper tension and keep it smooth. The ends of the lower roller C have their bearings in slotted plates e, se-

cured to the inside ofthe top rails of the frame A, which plates are adjust-able for the purpose of setting the rollers nearer together or farther apart, according to the thickness of fabrio and the tension required.` As the napped fabric leaves the cylinders B B' it is acted on by means of two brush-drums, D D', arranged one above and the other below the fabric, and rotated in the direction indicated by the arrows in Fig. 1. The upper brnshdrum D receives its rotation from a shaft, E, by means of a belt, f, and the lower druinD receives its rotation from the shaft E by means of a crossed belt, f. Shaft E receives rotation from the main shaft B by means of a belt, g. F F are two smoothing or evening rolls, between which the napped fabric passes after it is brushed by the drums D D.

G G1 G2 designate calender rollers, the lower one of which is covered with an elastic material, and has keyed on one end a spur- Wheel, h, which engages with a pinion, h', on a shaft, H. Shaft H is journaled at one end in a box, which is on a hand-lever, I, by depressing which the pinion h will be disengaged from the wheel h. Lever I is held up by means of a wedge, t'.

On shaft H is keyed a cone-pulley,j, around which a belt', 7s, passes. This belt le is also passed around a cone-pulley, k', on a drivingshaft, J, which is represented in Fig. l. The two rollers G Gl have xed bearings in standards rising from the frame A, and the top roller G2 is free to move up and down in slots made in said standards.

Figs. 3, 4, and 5 show my sectional spreader, which is put inside of the tubular fabric between the rolls F F and the calenderingrollers, as indicated in dotted lines, Fig. 2. This spreader is composed of two curved side sections, K K, and two tubular sections, L L, which latter receive tenons formed on the ends of the curved sections. The tubes L L will vary in length, according to the width required to stretch the fabric. To avoid undue friction I of the fabric on the stretcher, I use anti-friction cylinders, and brush-drums, arranged as described, of the smoothing or evening rollers, between Which'the napped fabric passes after it is brushed by the drums.

2. In a napping-machinqthe combination,

' with the adjustable friction-rollers, nappingmachine cylinders, brush-drums, and smoothin g-rollers, of the calendering-rol1ers, the lower one of which is covered with an elastic material.

3. .The stretcher for a napping-machine, composed of the curved sections K K and L L, in combination with the anti-friction rollers p, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. A
